Use acorn, butternut, carnival, dumpling, delicata, spaghetti, hubbard, or crookneck squash. (Pete Wolff preferred hubbard, Ashley Wolff prefers acorn)
Instructions
Halve squash lengthwise and remove seeds (for larger squash, such as hubbard or crookneck, cut into manageable pieces, like quarters or eights) and lay skin side down into a baking dish.
Add about a half inch of water to dish.
Put about half of a tablespoon of butter into each of the halves. Add EITHER salt and pepper (for a savory flavor) OR brown sugar (for a sweet and nutty flavor).
Also try maple syrup, instead of brown sugar.
Cover, and cook at 400° for about 45 minutes (or until squash is soft).
Let cool a bit and EITHER scoop out the squash and mash OR serve half as is!
